EDYIN S. RElD,-OF NE7 YORK, N. Y., ASSIGNOR TO THE STANDARD UN-DERGROUND CABLE COMPANY, OF PITTSBURG, PENNSYLVANIA.

SPECIFICATION forming part of Letters Patent No. 424,935, dated April 1,1890.

Application led January 1l, 1890. Serial No. 336,661. (No model.)

To all whom it may concern:

Be it known thatr l, EDWIN S. REID, a citizen of the United `States,residing at New York, in the county of New York and State of New York,have invented or discovered a certain new and useful Improvement inGrips for Drawing in Cables, of which improvement the following is aspecification.

The invention described herein relates to certain improvements in gripsfor drawing electric and other cables into conduits, dac. Heretofore indrawing in such cables one end thereof has had to be especially preparedfor attachment to the draw-in rope, and the cable is generally sodamaged by such attachment and the drawing-in operation as tonecessitate the cutting off of a considerable portion thereof.

The object of this invention is to provide a grip which can be securelyattached to the cable at any point without any injury thereto; and ingeneral terms the invention consists in the construction and combinationof mechanical devices or elements, all as more fully hereinafterdescribed and claimed.

ln the accompanying drawings, forming a part of this specification,Figure l is a sectional View of my improved grip applied to a cable.Fig. 2 is an end elevation of the same. Fig. 3 is a side elevation of amodified form of the grip. Fig. l is au end elevation of the same. Figs.5, 6, 7, and S are end elevations showing a construction of sectionalblock or wedge for drawing in one or more cables simultaneously.

In the practice of my invention a sleeve or shell Linternally tapered,as shown in Fig. l, is slipped over the end of the cable, with the endhaving the larger opening toward the front end of the cable. Two or moresectional blocks or Wedge-shaped pieces 2, having their inner facesstraight and concave or adapted to have a uniform even bearing or gripupon the cable, and their outer faces tapering from one end to the otherand convex transversely or otherwise shaped to fit with the sleeve orshell, are placed around the cable adjacent to its end and thesleeveslipped forward over the sectional blocks or wedges, clamping themaround the cable. The draw-in rope, which has been previously passedthrough the conduit, is connected to hooks 3 or other suitable means forattachment in the sleeve or ring, which is then drawn through theconduit, dragging the cable with it.

lt will be readily understood that the greater the power applied to theshell or sleeve to draw in the cable the tighter the grip will engagethe cable and prevent any slipping thereof.

lt is frequently necessary to take up slack in cables between man-holes,and in order that the grip may be conveniently applied to the cable thesleeve may be made in two parts hinged together at one side, as shown inFigs. 3 and 4, and at the opposite side provided with a hasp or othersuitable catch 4, for holding the parts together. A grip having itssleeve thus constructed may be readily applied at any point on thecable, thus 7o avoiding the necessity of slipping the ring or sleeve onat the end of the cable.

Vhile the wedges are shown as nearly surrounding the cable, forming aconical plug,

as it were, when arranged in position, they may be made so as to onlypartially surround the cable, as indicated by dotted lines in Fig. 2. Itis frequently desirable to draw in two or more cables simultaneously,and to that end the inner walls of the sectional blocks or 8o wedges areprovided with two or more cablegripping faces, as shown in Figs. 5 to S.In Fig. 5 is shown (in full lines) a construction of grip whereby one,two, three, or more cables may be drawn in simultaneously by thesectional blocks or wedges (two in number) having independentcable-gripping faces. By employing four sectional blocks or wedges, asindicated in full and dotted lines in Fig.

5, the capacity of the grip can be largely in- 9o creased. In Figs. 6,7, and S is shown a construct-ion of blocks or wedges having theirgripping-faces so arranged that the cables are forced into contact witheach other by the wedges. struction whereby five cables may be drawn in,four resting in the gripping-faces in the blocks or wedges and beingforced against a centrally-located cable.

The shape or construction of the sleeve or shell is immaterial, it onlybeing essential that `it have inner surfaces longitudinally taln Figs. Gand 7 is shown a con- 95 IOO pering or inelined and adapted by bearingupon exterior inelined blocks or wedges to force the latter toward eachother aud into engagement with the cable.

The wedges are preferably formed of wood or other like material, so thatthe cable may not be injured by eoutaet therewith.

I claim herein as my invention-- l. In a Cable-grip or drawingdnapparatus, two or more sectional blocks or wedges adapted by theirmovements toward each other to take a bite on one or more eables to bedrawn, and made with an exterior taper, in Combination with asurrounding shell or sleeve corre"- spondingly tapered as regards itsinner wall, and provided with engagingr devices by which to makeConnection with the pulling-power, substantially as set forth.
